Unfortunately, there is no way for users to enable OpenFlow on switches that do not support the functionality.

The easiest way to start experimenting with OpenFlow is to download the <a href="http://www.projectfloodlight.org/floodlight/" rel="nofollow">Floodlight</a> controller VM image. Floodlight is an open source OpenFlow controller written in Java. The virtual machine available on the download page is an Ubuntu based image. When you start up the image the Floodlight controller will already be running. The image also includes <a href="http://mininet.org/" rel="nofollow">Mininet</a> in it. Mininet allows the creation of virtual networks inside a single instance of Linux. this will allow you to create any arbitrary network topology of OpenFlow-enabled software switches and connect it to the Floodlight controller.

I want to run OpenFlow on a switch.

I have root privileges on a switch that does not support OpenFlow yet.

How can I make this switch support OpenFlow and then control traffic flow on it from outside the box?

Basically I want to start experimenting with OpenFlow. Where do I start from?

我想在交换机上运行OpenFlow。我在尚不支持OpenFlow的交换机上具有超级用户权限。如何使此交换机支持OpenFlow，然后从机箱外控制其上的流量？基本上，我想开始尝试使用OpenFlow。我从哪里开始呢？
